Urine is a product of human metabolism. It is formed by filtering blood in the kidneys, which is why the composition of urine gives a clear description of the state of the human body.
Urine is a complex solution of more than 150 compounds. Some specific substances, for example, acetone, bile acids, protein, glucose, can be present in the urine only in certain diseases.
To control human health, first of all, it is necessary to determine the amount of urine. The norm is the formation of 1-1, 8 liters of urine per day. When more than 2 liters of urine are released, this is a sign of a possible impairment in the functioning of the kidneys, diabetes mellitus and a number of other diseases. If less than 0.5 liters of urine is produced per day, there is a blockage of the ureter or bladder.
The color of urine excreted depends on many factors, so it can vary from light yellow to orange. The presence of certain shades can be affected by some food products, as well as medications taken by a person.
After taking medications, urine may become colored and reddish. If a person is actively moving, while he has a large amount of sweat, the urine will have an intense yellow color, as well as when taking funds such as "Nitroxoline" or "Biomycin".
If a person has not taken any coloring food and medicine, but the color of his urine is different from the usual one, one can suspect the presence of a disease in the body. For example, with liver disease, urine will be dark yellow or greenish in color.
The presence of blood in the excreted urine clearly indicates the presence of a stone in the ureter or renal bleeding, if pain is also observed.
If urination is difficult, this may indicate an inflammatory process caused by an infection in the bladder. But dirty and cloudy urine indicates severe kidney disease.
Protein in urine
In a person's blood, there is no protein or its amount is so small that it cannot be determined using laboratory tests. If protein is detected in the urine, it is necessary to retest, since it may be present when a person wakes up in the morning, as well as after hard physical work or stress in athletes.
It is 100% impossible to visually determine whether protein is present in the urine or not. One can only guess when there is a large amount of whitish flakes in the urine.
If protein is re-detected in the urine, it indicates the presence of some kind of kidney disease. The inflammatory processes occurring in them provoke a slight increase in the amount of protein. If more than 2 grams of it is excreted in the urine, this is an alarming signal.
